CPU利用率高，如何快速定位并采集信息？

当设备的利用率较高时，可以通过以下步骤快速定位并采集信息，然后反馈给技术支持人员进行处理。

执行display cpu命令查看CPU占用率高的服务名称。
<HUAWEI> display cpu
CPU utilization statistics at 2016-02-02 02:07:22 366 ms
System CPU Using Percentage : 6%
CPU utilization for five seconds: 6%, one minute: 6%, five minutes: 6%.
Max CPU Usage : 38%
Max CPU Usage Stat. Time : 2016-02-01 12:29:26 821 ms
State: Non-overload
Overload threshold: 90%, Overload clear threshold: 75%, Duration: 480s
---------------------------
ServiceName UseRate
---------------------------
SYSTEM 6%
AAA 0%
ARP 0%
CMF 0%
......

诊断视图下多次执行命令display system service service-name查看业务中CPU占用率高的组件。
